It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

A mobile terminal implementing various embodiments of the present invention will now be described with reference to the accompanying drawings. In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for facilitating the explanation of the present invention, and have no specific meaning in themselves.

For example, the terminal described in the present invention may include a mobile terminal such as a mobile phone, a smart phone, a notebook computer, a digital broadcast receiver, a PDA (personal digital assistant), a PAD (tablet computer), a PMP (portable multimedia player), a navigation device, and the like, and a stationary terminal such as a digital TV, a desktop computer, and the like. In the following, it is assumed that the terminal is a mobile terminal. However, it will be understood by those skilled in the art that the configuration according to the embodiment of the present invention can be applied to a fixed type terminal in addition to elements particularly used for moving purposes.

Fig. 1 is a schematic hardware configuration of a mobile terminal implementing various embodiments of the present invention.

The mobile terminal 100 may include a wireless communication unit 110, an a/V (audio/video) input unit 120, a user input unit 130, a sensing unit 140, an output unit 150, a memory 160, an interface unit 170, a controller 180, and a power supply unit 190, etc. Fig. 1 illustrates a mobile terminal having various components, but it is to be understood that not all illustrated components are required to be implemented. More or fewer components may alternatively be implemented. Elements of the mobile terminal will be described in detail below.

The wireless communication unit 110 typically includes one or more components that allow radio communication between the mobile terminal 100 and a wireless communication system or network. For example, the wireless communication unit may include a mobile communication module 111.

The mobile communication module 111 transmits and/or receives radio signals to and/or from at least one of a base station (e.g., access point, node B, etc.), an external terminal, and a server. Such radio signals may include voice call signals, video call signals, or various types of data transmitted and/or received according to text and/or multimedia messages. For example, in the embodiment of the present invention, the number of the mobile communication modules 111 is preferably two, and the mobile communication modules 111 are used to respectively implement the first modem processing module and the first radio frequency module, and the second modem processing module and the second radio frequency module of the embodiment of the present invention.

The a/V input unit 120 is used to receive an audio or video signal. The a/V input unit 120 may include a microphone 121, and the microphone 121 may receive sounds (audio data) via the microphone in a phone call mode, a recording mode, a voice recognition mode, or the like, and may be capable of processing such sounds into audio data. The processed audio (voice) data may be converted into a format output transmittable to a mobile communication base station via the mobile communication module 111 in case of a phone call mode. The microphone 121 may implement various types of noise canceling (or suppression) algorithms to cancel (or suppress) noise or interference generated in the course of receiving and transmitting an audio signal. In an embodiment of the present invention, the microphone 121 is used to implement a digital signal processing module and a voice input module of an embodiment of the present invention.

The user input unit 130 may generate key input data according to a command input by a user to control various operations of the mobile terminal. The user input unit 130 allows a user to input various types of information, and may include a keyboard, dome sheet, touch pad (e.g., a touch-sensitive member that detects changes in resistance, pressure, capacitance, and the like due to being touched), scroll wheel, joystick, and the like. In particular, when the touch pad is superimposed on the display unit 151 in the form of a layer, a touch screen may be formed.

The sensing unit 140 detects a current state of the mobile terminal 100 (e.g., an open or closed state of the mobile terminal 100), a position of the mobile terminal 100, presence or absence of contact (i.e., touch input) by a user with the mobile terminal 100, an orientation of the mobile terminal 100, acceleration or deceleration movement and direction of the mobile terminal 100, and the like, and generates a command or signal for controlling an operation of the mobile terminal 100. For example, when the mobile terminal 100 is implemented as a slide-type mobile phone, the sensing unit 140 may sense whether the slide-type phone is opened or closed. In addition, the sensing unit 140 can detect whether the power supply unit 190 supplies power or whether the interface unit 170 is coupled with an external device.

The interface unit 170 serves as an interface through which at least one external device is connected to the mobile terminal 100. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device having an identification module, an audio input/output (I/O) port, a video I/O port, an earphone port, and the like. The identification module may store various information for authenticating a user using the mobile terminal 100 and may include a User Identity Module (UIM), a Subscriber Identity Module (SIM), a Universal Subscriber Identity Module (USIM), and the like. In addition, a device having an identification module (hereinafter, referred to as an "identification device") may take the form of a smart card, and thus, the identification device may be connected with the mobile terminal 100 via a port or other connection means. The interface unit 170 may be used to receive input (e.g., data information, power, etc.) from an external device and transmit the received input to one or more elements within the mobile terminal 100 or may be used to transmit data between the mobile terminal and the external device.

In addition, when the mobile terminal 100 is connected with an external cradle, the interface unit 170 may serve as a path through which power is supplied from the cradle to the mobile terminal 100 or may serve as a path through which various command signals input from the cradle are transmitted to the mobile terminal. Various command signals or power input from the cradle may be used as signals for recognizing whether the mobile terminal is accurately mounted on the cradle. The output unit 150 is configured to provide output signals (e.g., audio signals, video signals, alarm signals, vibration signals, etc.) in a visual, audio, and/or tactile manner. The output unit 150 may include a display unit 151, an audio output module 152, and the like.

The display unit 151 may display information processed in the mobile terminal 100. For example, when the mobile terminal 100 is in a phone call mode, the display unit 151 may display a User Interface (UI) or a Graphical User Interface (GUI) related to a call or other communication (e.g., text messaging, multimedia file downloading, etc.). When the mobile terminal 100 is in a video call mode or an image capturing mode, the display unit 151 may display a captured image and/or a received image, a UI or GUI showing a video or an image and related functions, and the like.

Meanwhile, when the display unit 151 and the touch pad are overlapped with each other in the form of a layer to form a touch screen, the display unit 151 may serve as an input device and an output device. The display unit 151 may include at least one of a Liquid Crystal Display (LCD), a thin film transistor LCD (TFT-LCD), an Organic Light Emitting Diode (OLED) display, a flexible display, a three-dimensional (3D) display, and the like. Some of these displays may be configured to be transparent to allow a user to view from the outside, which may be referred to as transparent displays, and a typical transparent display may be, for example, a TOLED (transparent organic light emitting diode) display or the like. Depending on the particular desired implementation, the mobile terminal 100 may include two or more display units (or other display devices), for example, the mobile terminal may include an external display unit (not shown) and an internal display unit (not shown). The touch screen may be used to detect a touch input pressure as well as a touch input position and a touch input area.

The audio output module 152 may convert audio data received by the wireless communication unit 110 or stored in the memory 160 into an audio signal and output as sound when the mobile terminal is in a call signal reception mode, a call mode, a recording mode, a voice recognition mode, a broadcast reception mode, or the like. Also, the audio output module 152 may provide audio output related to a specific function performed by the mobile terminal 100 (e.g., a call signal reception sound, a message reception sound, etc.). The audio output module 152 may include a speaker, a buzzer, and the like. In an embodiment of the present invention, the audio output module 152 is used to implement a voice output module in an embodiment of the present invention.

The memory 160 may store software programs and the like for processing and controlling operations performed by the controller 180, or may temporarily store data (e.g., a phonebook, messages, still images, videos, and the like) that has been or will be output. Also, the memory 160 may store data regarding various ways of vibration and audio signals output when a touch is applied to the touch screen.

The memory 160 may include at least one type of storage medium including a flash memory, a hard disk, a multimedia card, a card-type memory (e.g., SD or DX memory, etc.), a Random Access Memory (RAM), a Static Random Access Memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, an optical disk, and the like. Also, the mobile terminal 100 may cooperate with a network storage device that performs a storage function of the memory 160 through a network connection.

The controller 180 generally controls the overall operation of the mobile terminal. For example, the controller 180 performs control and processing related to voice calls, data communications, video calls, and the like. The controller 180 may perform a pattern recognition process to recognize a handwriting input or a picture drawing input performed on the touch screen as a character or an image. For example, in the present embodiment, two controllers 180 are preferred for implementing the first application processing module and the second application processing module of the embodiment of the present invention, respectively.

The power supply unit 190 receives external power or internal power and provides appropriate power required to operate various elements and components under the control of the controller 180.

The software codes may be implemented by software applications (or programs) written in any suitable programming language, which may be stored in the memory 160 and executed by the controller 180.

Up to this point, mobile terminals have been described in terms of their functionality. Hereinafter, a slide-type mobile terminal among various types of mobile terminals, such as a folder-type, bar-type, swing-type, slide-type mobile terminal, and the like, will be described as an example for the sake of brevity. Accordingly, the present invention can be applied to any type of mobile terminal, and is not limited to a slide type mobile terminal.

Referring to fig. 2, fig. 2 is a diagram illustrating an example topology of a dual modem system of a mobile terminal implementing various embodiments of the present invention, and as shown in fig. 2, the mobile terminal may include a first communication system 10 and a second communication system 20 connected to each other (e.g., connected through a Universal Serial Bus (USB)).

The second application processing module 201 is a processor with a relatively weak processing capability compared to the first application processing module 101, and only plays a role of transparent transmission, that is, data, information, and the like are not processed, but are directly transmitted to the first application processing module 101 or the second modem processing module 202.

When the mobile terminal 100 interacts with the operator network, whether internet access is performed through data traffic, Voice over LTE (Voice over LTE) call is performed, or CS (Circuit Switched) call is performed, all of which pass through the protocols of these standards. The first modem processing module 102/the second modem processing module 202 have other administrative functions, including management and control of the subscriber identity cards, for example, as shown in fig. 2, two subscriber identity cards are connected to the first modem processing module 102 (in other embodiments, the number of subscriber identity cards connected to the first modem processing module 102 is set according to actual needs, for example, only one subscriber identity card may be connected), which are the first subscriber identity card and the second subscriber identity card, respectively.

a second application processing module 201, configured to set a third logical port corresponding to the first logical port, and set a fourth logical port corresponding to the second logical port;

the second logical port and the fourth logical port are used for transmitting control commands.

In the embodiment of the present invention, to implement data and signaling transmission between the first application processing module 101 and the second application processing module 201, the first application processing module 101 sets a first logical port and a second logical port, the second application processing module 201 sets a third logical port corresponding to the first logical port, and sets a fourth logical port corresponding to the second logical port. The first logical port and the third logical port form a data channel of the first application processing module 101 and the second application processing module 102, and are used for transmitting data between the first application processing module 101 and the second application processing module 201; the second logical port and the fourth logical port constitute a control channel between the first application processing module 101 and the second application processing module 201, and are used for transmitting a control command between the first application processing module 101 and the second application processing module 201. Specifically, when the first application processing module 101 sets the first logic port and the second logic port, the first logic port and the second logic port may be directly set, or when the third logic port and the fourth logic port set by the second application processing module 201 are detected, the first logic port and the second logic port may be set, specifically according to actual needs. For example, in the present embodiment, the first application processing module 101 and the second application processing module 201 are connected via a universal serial bus (in other embodiments, the first application processing module 101 and the second application processing module 201 may also be connected via an I2C bus, or other connection means not shown), the first logical port and the second logical port set by the first application processing module 101 are respectively a first ethernet control model port and a first modem port, and the third logical port and the fourth logical port set by the second application processing module 201 are respectively a second ethernet control model port and a second modem port, wherein the first ethernet control model port and the second ethernet control model port constitute a data channel of the first application processing module 101 and the second application processing module 102, the first modem port and the second modem port constitute control channels of the first application processing module 101 and the second application processing module 102.

Further, in this embodiment, the mobile terminal 100 further includes:

For example, when receiving the upstream network data from the first application processing module 101 through the third logical port, the second application processing module 201 directly passes the received upstream network data to the second modem processing module 202, and the second modem processing module 202 sends the upstream network data; when receiving a control instruction corresponding to the second modem processing module 202 from the first application processing module 101 through the fourth logical port, the second application processing module 201 directly passes the received control instruction to the second modem processing module 202, and the second application processing module 202 executes the control instruction; the second application processing module 201 executes the received control instruction when receiving the control instruction corresponding to the second application processing module 202 from the first application processing module 101 through the second logical port.
